I’m travel solo and I want to go to the Great Wall from Beijing what’s your recommendation thank you

Well, you need to plan your schedule in advance. First, which section of the Great Wall would you like to visit? Since you are the first-time traveler, the Badaling and Mutianyu are most recommended. Second, if you want to go there by public transportation, you need to know about the traffic information in advance, especially the bus itinerary and time. Surely a private day tour can be a good choice to save your time. Hope helpful.
